1235 bordeaux drive, sunnyvale, ca 94089 t el: 408-222-8888 www .supertex.com hv441 general description the supertex hv441 is a monolithic integrated circuit capable of generating up to a 70v rms sine wave output at frequencies of 15 to 60hz with a load of 5 north american rens. its output rating can be enhanced to 20 north american rens with the addition of two supertex mosfets: one n-channel mosfet, the tn2524n8, and one p-channel mosfet, the tp2522n8. the high voltage outputs have pulse by pulse over-current protection set by two external sense resistors. the hv441 generates a low voltage reference sine wave by using external passive components. an external sine wave signal can be used if desired. the hv441 ampli?es the reference sine wave signal by pulse width modulating the high voltage output at a nominal frequency of 100khz. an error ampli?er compares the output sine wave with the reference sine wave and adjusts the pulse width accordingly. both the amplitude of the output sinewave and the dc offset voltage are adjustable. for detailed circuit and application information, please refer to application note an-h35. functional block diagram features 220v maximum operating voltage integrated high voltage transistors up to 70 v rms ring signal adjustable ac and dc output voltage level adjustable ring signal start phase angle pulse by pulse output over current protection 5 ren output capability external mosfets enhance output rating to 20 ren applications stand alone high voltage ring generator set-top/street box ring generator pair gain ring generator wireless local loops fibre in the loop/to the curb coax cable loop ? ? ? ? ? ? ? ? ? ? ? ? ? ? high voltage ring generator ic hig h voltage leve l translato r pulse width regulator output2 input2 - input2 + input1 - input1 + input3 - input3 + output3 output1 op-amp 2 op-amp 1 op-amp 3 com p 4 osc1 osc2 osc(in) osc(out ) gnd v dd1 v dd2 v dd2 v dd2 v dd2 vdd2 vref vdd1 zero voltage crossing detection linea r reg vpp1 v dd2 vpsen vpgate vpp2 hvout pgn d current sense an d drive r vnn2 vnse n vngate vnn1 + C + C - + - + on/off hig h voltage leve l translato r osc ramp generato r current sense an d drive r linea r reg
